Cloudflare DNS (1.1.1.1) down?

[Spork829]

Just now I couldn't connect to anything on my main pc, but everything else on the network was still working. It occurred to me that I had changed this machine to that newfangled DNS server LTT made a video about a while ago. I changed it back to Google DNS and things are working. Interesting.

Might be. Also using cloudflare dns and Im having issues as well

Yep, looks like they're reporting an outage, I wonder what the cause is

I couldn't connect to any dns servers - no dns traffic was being received at all - but routing was still working properly using IP addresses. I was on Cloudflare, changed to Google with a /flushdns, and then changed to OpenDNS - all had zero response. Even rebooted my machine and tried on my mac (which has never used Cloudflare or OpenDNS, only Google DNS), no effect.

 

Rebooted my router and I'm now on a different route and have full access to dns again.

 

Some weird sinkholing of popular DNS server traffic? Even a few seconds of that would give someone wide-ranging insight into the browsing habits of millions of people.

Yeah, that's really strange. I was able to just swap over and reboot without any issues.

Seems to be back up. Back on wifi on the phone.

That was crazy fast. Looking at the status page, their reports of DNS timeouts and them implementing a fix are a minute apart... 0_0

I did a traceroute to 1.1.1.1 (Primary Cloudflare public DNS), 8.8.8.8 (Primary Google public DNS) and 208.67.222.222 (Primary OpenDNS public DNS), and the routes before I rebooted my router and after I rebooted my router were completely different.

 

I really wish I had kept the output now, I rebooted my machine after running those tests but before restarting my router. It would have proven interesting.

If you've changed it in Windows, you could've just set the primary DNS as 1.1.1.1 and the alternative DNS as the one from your ISP instead of using both the cloudflare DNS.

That way if it ever goes down, you at least won't be losing your network connection.
(Or better yet, straight in your router, where you can generally input more than two static DNS, I can do three on DD-WRT, which are 1.0.0.1 (cloudflare), 8.8.8.8(google) and my ISP's)

Good idea, I should probably set it on the router as well

That's what I did on my router ; cloudflare DNS, then Google, then my ISP
